Illuminating Electrical Fuse

Abstract

An illuminating electrical fuse having an indicator lamp is provided. The indicator lamp is connected to the fuse element on the load side of the circuit and to an independent ground. During operation of the fuse, the lamp is illuminated. When the fuse blows out, the lamp is extinguished. The configuration of the circuit places the lamp in parallel with the circuit load in contrast to similar fuses having the lamp, fuse element and load in series. With the lamp in parallel, lamp failure does not shut down the circuit. Further, the current draw of the electrical load bypasses the lamp circuit through which only a small current passes. The lamp in the preferred embodiment is a light emitting diode.
